Frequently Asked Questions about Ferric Ammonium Citrate for Cyanotype

What exactly is ferric ammonium citrate and what do you use it for?

Ferric ammonium citrate (green) is a light-sensitive compound used in cyanotype as part of the emulsion that makes blueprints possible. In combination with potassium ferricyanide it forms a UV-reactive layer that turns blue when exposed to light.

What role does this substance play in the cyanotype process?

It yields the iron(III) ion which is reduced under UV light to iron(II), which then reacts with potassium ferricyanide to form the characteristic blue of Prussian Blue.

How do I mix ferric ammonium citrate for use in cyanotype?

Mix in equal parts with potassium ferricyanide, each dissolved in distilled water. Combine just before use in a dark or dim room, and apply the mixture to paper or fabric.

What is the best way to store ferric ammonium citrate?

Dry and cool, in a well-sealed container away from direct sunlight. Ideally below 20°C. Avoid moisture – it is hygroscopic and will clump together quickly when exposed to humidity.

Frequently Asked Questions about Ferric Ammonium Citrate for Cyanotype

Is ferric ammonium citrate safe?

Yes, when used correctly. Wear gloves, avoid inhalation of powder and avoid contact with skin and eyes. Keep out of reach of children.

Is this the same as ammonium ferric citrate?

Yes, this is the Dutch name for the same compound: ammonium iron citrate (green). Other synonyms are iron(III) ammonium citrate, ferric citrate ammonium, or EINECS 235-614-9.

What is the difference between green and brown ferric ammonium citrate?

Green contains a higher percentage of iron (~15%) and is most commonly used for cyanotype. The brown variety contains less iron and is rarely used for this purpose.

How many prints can I make with 100g or 500g?

With 100g you can make about 100–120 A5 prints in normal use. 500g is good for about 500–600 prints, depending on your coating technique and paper choice.
